We have two ESX hosts at our DMZ zone with a firewall running between them and the Virtual Center Server. The ESX hosts have been managed under the Virtual Center Server since September 2007
Today, we applied the latest November 2007 patches to 1 of the server and after the reboot we found that the hosts will not stay connected with our virtual center server. We can connect it manually and it will stay connected for about 30 seconds to 1 minute and then disconnected again.
Without doing any changes on the 2nd host, we did a reboot and it exhibit the same symptoms (keeps disconnecting from Virtual Center)
The two ESXT hosts are both running under ESX 3.01, 1 at patch level 42829 and 1 at patch level 60875. The virtual center server is running VC 2.01
We checked with the network team and they said all the ports that we needed for VI3 are opened:
VC --> ESX host:902/tcp
VC --> ESX host:903/tcp
ESX host:902/udp --> VC (UDP heartbeat)
ESX host --> VC:27000/tcp
ESX host --> VC:27010/tcp
We have other ESX hosts running under our coporate network without the firewall. We just patch 1 host to 60875 and this host has no connection problem. Everything is running fine.
Please help!!
